FIELD: electricity.
SUBSTANCE: light emitting diode (LED) of bulb-type lamp (1) has bulb (3) installed on base. Light source (7) containing many LEDs installed on printed-circuit board (9) is located inside bulb (3). Printed-circuit board (9) operates as and/or is connected to cooling means (21). Outer surface (15) of bulb is formed both as transparent surface and/or its subareas and cooling means (21). These cooling means pass from the bulb inside to the bulb outer surface. Surfaces are mutually flush levelled in places on outer surface of the bulb where mentioned surfaces of cooling means and transparent subareas adjoin.
EFFECT: improving spatial spread of lamp light intensity.
